Preventing Mold: 9 Tips That Help Prevent Mold

The Maids • Oct 22, 2011

Preventing mold, a microscopic fungus, is something that every homeowner should keep in mind. These fungi, once grown, reproduce at a rapid rate, producing spores and mycelia in the process. Some people may not think that preventing mold is a big deal; you see food spoilage due to mold, wood and leaves decaying due to mold. What most people may not know is that mold can be harmful and may affect the occupants of a home; therefore, preventing mold is a serious matter.

Preventing mold can save your house from looking like this.

Mold can cause damages to both materials it grows on as well as an occupant’s health. Mold on a material may cause discoloration or staining, cause paper or cardboard to disintegrate over time, and can also cause wood rot and structural damage. When it comes to health concerns, mold releases chemicals and spores which, depending on the type of mold and level of exposure, may cause allergic reactions and illness to those who are exposed. This is why people should be concerned with preventing mold. Those with health problems and weakened immune systems, such as pregnant woman, infants, and elders, are more at risk when exposed to mold. Knowing how to prevent mold before it starts can help keep your family and all that enter your home safe. 

Preventing mold is a bigger deal then some may think. When you see that black fuzzy growth on a wet window sill, you may not realize that it's mold. Mold is attracted to damp and moist areas. Mold can occur from moisture coming into your home from the outside through the floor, walls, plumbing leaks, or even by daily life activities of the homeowner: bathing, washing clothes, and cooking. Preventing mold from coming into your house in the first place may be hard, but the following article on Mothernaturenetwork.com offers 9 tips on how you can be preventing mold in your home.

How to prevent mold: 9 tips

The key to preventing mold is simple: Moisture control.

Mold. The very word is enough to make a person cringe.

Yes, mold can be good — it's essential in making brie and penicillin, for example, and necessary for the decomposition of organic matter in nature — but it can also be very, very bad, especially when it grows undetected in your home.

Mold spores spread easily and cannot be completely eradicated.

Mold can grow anywhere: on carpet, clothing, food, paper, and even in places you can't see, such as the backside of drywall, areas inside walls around leaking or condensing pipes, and above ceiling tiles.

Not only is a mold problem difficult and costly to fix, but mold can also produce allergens and irritants (and, rarely, toxins) that may compromise your health.

So what can you do if you're concerned about mold growing in your home?

The best approach is preventing mold before it becomes a problem. The key to mold prevention is simple: moisture control.

Here are nine ways to curb moisture indoors, and the mold that thrives on it.

  1. Identify problem areas in your home and correct them. You can't mold-proof your home, but you can make it mold-resistant. Do an audit of your home: where are the problem areas? Does the basement flood? Do you notice frequent condensation on an upstairs window? Is there a water stain on the ceiling from a persistent leak? Preventing mold from growing or spreading might be as simple as ripping up carpet in a damp basement, installing mold-resistant products, or repairing damaged gutters. Or it may be a matter of major excavation and waterproofing. Whatever the case, address the problem now. It might cost some money up front, but it will surely be more costly down the road if mold continues to grow unchecked.
  1. Dry wet areas immediately. Mold can't grow without moisture, so tackle wet areas right away. Seepage into the basement after a heavy rainfall, accumulation from a leaky pipe, even a spill on the carpet should be dried within 24 to 48 hours. If you've experienced a flood, remove water-damaged carpets, bedding, and furniture if they can't be completely dried. Even everyday occurrences need attention: don't leave wet items lying around the house, and make sure to dry the floor and walls after a shower. Don't leave wet clothes in the washing machine, where mold can spread quickly. Hang them to dry — preferably outside or in areas with good air circulation.
  1. Prevent moisture with proper ventilation. It may be that your routine domestic activities are encouraging the growth of mold in your home. Make sure an activity as simple as cooking dinner, taking a shower, or doing a load of laundry doesn't invite mold by providing proper ventilation in your bathroom, kitchen, laundry room, and any other high-moisture area. Vent appliances that produce moisture — clothes dryers, stoves — to the outside (not the attic). Use AC units and dehumidifiers (especially in humid climates), but make sure they don’t produce moisture themselves by checking them periodically and cleaning them as directed by the manufacturer. Your energy-efficient home may be holding moisture inside, so open a window when cooking or washing dishes or showering, or run an exhaust fan.
  1. Equip your home with mold-resistant products. Building a new home or renovating an old one? Use mold-resistant products like mold-resistant drywall or mold-resistant Sheetrock, and mold inhibitors for paints. Traditional drywall is composed of a gypsum plaster core pressed between plies of paper. Mold-resistant drywall is paperless — the gypsum core is covered in fiberglass, making the surface highly water-resistant. Moisture-resistant drywall is especially valuable in areas prone to wetness, such as bathrooms, laundry rooms, basements, and kitchens. Not only is traditional drywall more susceptible to mold than the paperless kind, but it is also difficult to rid of mold, and removal and replacement can be expensive. Mold-resistant gypsum board is also available; the core of the drywall is developed in such a way to prevent moisture absorption, and thus prevent mold growth.
  1. Monitor humidity indoors. The EPA recommends keeping indoor humidity between 30 and 60 percent. You can measure humidity with a moisture meter purchased from your local hardware store. You'll also be able to detect high humidity by simply paying attention to potential problem areas in your home. Telltale signs of excessive humidity include condensation on windows, pipes, and walls. If you notice condensation, dry the surface immediately and address the source of moisture (for example, turn off a humidifier if water appears on the inside of nearby windows).
  1. Direct water away from your home. If the ground around your home isn't sufficiently sloped away from the foundation, water may collect there and seep into your crawlspace or basement.
  1. Clean or repair roof gutters. A mold problem might be a simple matter of a roof that is leaking because of full or damaged gutters. Have your roof gutters cleaned regularly and inspected for damage. Repair them as necessary, and keep an eye out for water stains after storms that may indicate a leak.
  1. Improve air flow in your home. According to the EPA, as temperatures drop, the air is able to hold less moisture. Without good air flow in your home, that excess moisture may appear on your walls, windows and floors. To increase circulation, open doors between rooms, move furniture away from walls, and open doors to closets that may be colder than the rooms they’re in. Let fresh air in to reduce moisture and keep mold at bay.
  1. Keep mold off household plants. They're beautiful and help keep your indoor air clean — and mold loves them. The moist soil in indoor plants is a perfect breeding ground for mold, which may then spread to other areas of your house. Instead of getting rid of your plants, try adding a bit of Taheebo tea to the water you give to your houseplants. The oil of this tree, which withstands fungi even in rain forests, helps hinder mold growth in plant soil and can be found at natural food stores.

Finally, educate yourself on your region's climate — be it the cold and wet Northeast, the hot and wet South, the hot and dry Southwest, or the cold and dry West — and how it responds to moisture. There is no one-size-fits-all solution when it comes to mold prevention. Knowing what works for your climate and your home is an important first step.

Preventing mold is sometimes out of your control; if mold makes its way into your home, take action right away. The sooner you clean up the mold the better off you are from preventing mold growth in the future. You can determine how much mold your home has by looking at the size and amount of patches you find in a given area. For mold to be considered a small amount, there should be no more than three patches greater in size than a square meter. If you have small amounts of mold, preventing mold growth from continuing, use a detergent solution or bleach is the best way to kill it.

If there is an extensive amount of mold found -- a single patch larger in area than a sheet of plywood -- it’s time to call in professional help. That amount of mold is not healthy to be around. As you can see, preventing mold is a serious matter and preventing mold from making its way into your home is your best option for keeping your family, as well as your home, safe.
